Does any F-1 student have experience traveling Nepal through London changing airlines in London? I am thinking to travel to Nepal via London and wondering if I need to get the transit visa. I did little research and my conclusion so far is if we (F-1) are not changing the airlines/airport in London we are exempt from the requirement to hold a Direct Airside Transit Visa (DATV). Bottom of page: http://www.ukvisas.gov.uk/servlet/Front?pagename=OpenMarket/Xcelerate/ShowPage&c=Page&cid=1020786334922 But if we are changing airlines/airport in London we need to get VISITOR-IN-TRANSIT visa.
